Police have a person in custody and have lifted a shelter-in-place order after an early morning explosion in Elsmere, Delaware.

The Delaware State Fire Marshal's office has charged Mark J. Consiglio, 48, of Elsmere, with 3 counts of manufacturing, possession and use of an explosive device after allegedly setting off an explosive device outside of the home where his estranged wife was staying Monday.

Investigation underway in Elsmere: Sarah Bloomquist and Rick Williams report during Action News at Noon on March 12, 2018.

Bags full of evidence were removed from the home on the 700 block of Baltimore Avenue. Officials said three additional explosive devices were recovered. Also taken was what appeared to be a firearm and a sword.

Amy Consiglio said her ex-husband has been threatening her ever since they separated.

"I'm hoping that my mom's OK. She's older. She shouldn't have to deal with this," she said. "I'm just happy that the law did what they are supposed to do."

Officials said Consiglio is expected to be arraigned Tuesday night and additional charges are expected.
